BELT mun mnonnmsm non WRAPPING MACHINES.

Application filed August 1, 1923.

'lhis invention relates to a. belt feeding inechanisln :lor caramel wrapping machines and the manner of incorporating the same in the machine.

a It is an object of this invention to provide a smooth belt il'teedinpf mechanism that conveys the caraniels to the wrapping wheel so that they can be injected therein; the smooth surface of the belt allowing the to caramels to be injected without the same being distorted or jammed in any way between the injecting plunger and the wrapping wheel consequently, a more accurate feed, with a higher rate of speed is possible.

is Hitherto, a great deal of diiiirulty has resulted in the use or attempt to use such a belt feed on account of the wave or weave in the traveling belt. This objecticui has been overcome in the manner of supporting an and guiding the belt. The invention consists in the novel l'llGiClldllltEilll and combinations hereinafter described and more par ticularly pointed out and delincd in the appended claims.

iii In the accompanying drawings which illustrate a preterred embodiment oil? this in vention and in which similar reference nunlerals refer to similar features in the different views.

fzli On the drawings:

Figure l is a top plan view of the feeding mechanism with a portion oil: the gear casing of the machine shown in section.

Figure 2 is a sectional view upon the line as 2--2 of Fig. 1.

Figure 3 is a side elevational view of the 'leeding mechanism with a fragmentary view of machine that is adjacent tl'ieroto and parts omitted.

Figure l is a sectional view upon the line d lof Fig. 1.

As shown onjhe drawings:

In referring now to the drawing, the rel?- erence numeral l indicates the gear casing 45 of: the caramel wrapping machine to which this invention is applied. A hearing pedestal 2 is secured to this casing and projects horizontally therefrom for supporting the wrapping wheel 3. the folding uiecluuiisin 5B and ejector not being illustrated, since the same involve no part of this invention. The :leed belt travels adjacent the wrappii'ig wheel 3 and the earan'iels with appropriate wrappers are periodically injected into the Serial No. 655,057.

wrapping wheel by an. injector a which 55 slides through a suitable guide be); (i.

A. food table 7 is suitably sup iiorted adjacent the wrapping wheel 3. The inner up per and lower margins of this table are rabheted as indicated at 8 in Fig. 2. to provide 60 guidcways in which the belt l travels and to allow the injector 5 to more over the table without interfering with the belt. Upon the far edge of the table there is secured a vertical guide strip 9 which extends from the outermost end of the table 7 to a point adjacent the outer side of. the wrapping wheel 3. This strip 9 forms a guide for the upper lap of the belt l upon which the caralnels are conveyed and causes the upper lap of said belt to travel in a straight line without any lateral movements.

Cooperating with the guide 9 there is another guide strip 10 secured to the top of the table and having its lower edge .rabbeted on the farsidc. As shown in Fig. 4-, the rabbeted portion overlaps the upper lap of the belt thus preventing the same from weaving in its travel.

The belt 4; is trained over a flanged pulley 11 secured upon a shaft 12 journalled in a suitable bearing bracket extending from the casing. A gear wheel 13 secured upon this shaft and is driven by a gear let upon a shaft 15 which is geared to the main drive of the machine. A guide roller 16 is sup ported upon the bracket 12 and its lower periphery is in the plane oi. the upper rabbeted portion of the table 7. At the outermost end of the food table there is a bracket 17 upon which an adjustable vertical arm 18 is pivotally mounted. A flanged pulley 19 is rotatably supported upon the arm '19 with its upper periphery in the plane of the upper rabbeted portion of the table 7. A spring pressed rod 20 is connected to the arm 18 and slidably extends through a bearing lug 21 upon the bracket 17. Adjustable nuts are secured upon the end oi the rod 20 and abut the bearing lu 521. By n'operly ad- 100 justing these nuts, the arm 18 may be swung to regulate the tension of the belt l as is obvious. A guide flanged roller 2:2 (Fig. 3) is rotatably supported by a suitable hearing secured to the bottom of the table. and sup 105 ports the lower lap of the belt in the lower rabbet of the table 7.

From the foregoing it will be apparent that a novel form of belt feed has been provided in which the belt is guided against weaving and against lateral movement and in which the guides 9 and 10 not only aid in uiding the belt butvalso provide lateral gui es for the caramels as they are conveyed on the belt.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a caramel wrapping machine, the combination with a caramel wrapping wheel, of a feeding mechanism therefor comprising a table having upper and lower rabbeted margins at oneedge, a belt conveyor having its upper and lower laps positioned in said rabbeted margins, a guide upon said table overlapping said belt and a lateral member upon the edge of the table for guiding the outer edge of said belt.

2. In a candy wrapping machine, the combination with the wrapping mechanism thereof, of candy feeding mechanism therefor, comprising a table, a flanged pulley supported at each end of said table, a belt trained over said pulleys, said table having upper and lower grooves, means for guiding and maintaining opposite portions of said belt in said grooves, and means for overlapping the upper lap of said belt to prevent weaving thereof.

In testimony whereof I have hereunto subscribed my name.
